摘　　要：针对四旋翼无人机导航定位精度较低的问题,提出了采用GPS/BDS双模导航对无人机进行制导与定位的方法,阐述了四旋翼无人机在BDS单系统、GPS单系统和GPS/BDS组合系统3种模式下的航行测试过程,分析研究了这3种模式下的可见卫星数和HDOP值。结果表明:在BDS单系统模式下可见卫星数较多且较稳定;在GPS单系统模式下具有较小的HDOP值;GPS/BDS组合系统模式可结合两者优势,具有最好的导航定位效果。In view of the four rotor unmanned aerial vehicle （uav） navigation and positioning problem of low accuracy, this pa- per launches a solution of uav GPS/BDS dual-mode navigation and positioning method applied to the uav.By comparing the number of visible satellites and HDOP value in autonomous navigation test with single BDS, single GPS and GPS/BDS module respectively, conclusions are drawn below. More visible satellites and stability can be found with BDS module, while smaller HDOP value is gotten with GPS module. GPS/BDS positioning method can combine both advantages of BDS and GPS modules, and has the best positioning effects.
